In large industrial buildings it can be useful to track the position of work equipment (robots, machines, vehicles) or goods (pallets, boxes). Indoor asset tracking is the solution. The object to be tracked is equipped with a beacon and can thus transmit its position continuously. If an object leaves a certain area (geofencing), an alarm can be triggered. This technology is also an option for hospitals, which want to determine the position of medical devices or hospital beds. It can also be applied to office buildings, airports and any other great building complex.
